Half the sample was told the current per-pupil spending in their district before being asked if they favored more, less or the same funding; the other half wasn’t provided any information.

Among respondents not told actual spending levels, only 53 percent support higher funding, down 10 percentage points from the 63 percent who were supportive a year ago. Information about current spending decreases support for higher levels of spending. Among those told how much local schools currently spend, support for spending increases was 43 percent, the same as a year previously.

The average person estimated their local district spends “$6,680 per pupil, hardly more than 50 percent of the average actual expenditure level of $12,637 per pupil in the districts where respondents live.”

In 2013, 55 percent of respondents not informed of current pay levels favor increases in teacher pay, down from 64 percent taking that position a year ago. Meanwhile, only 37 percent of those informed of salary levels favor an increase, virtually the same as the 36 percent taking that position in 2012. Once again, we cannot attribute the change to better knowledge of actual salary levels, as average estimates of salary levels remain essentially unchanged at $36,428, about $20,000 below actual average salaries in the states where respondents live.

Support for performance pay remains at 49 percent, but “opposition to basing teacher salaries in part on student progress has grown from 27 percent to 39 percent over the past two years.”

Opposition to vouchers for all students increased from 29 percent in 2012 to 37 percent this year.

Fewer people were neutral about charter schools: support moved up from 43 to 51 percent, while opposition increased from 16 to 26 percent.

Nearly two-thirds of Americans support Common Core standards in their state,though opposition is growing, the survey found.
